CAR-DOOR RIGGING.

Application filed .Tune 7, 1913.

Toall whom it may concern:

Be it known that I, RALPH V. SAGE, a c1tizen of the United States,residing in the borough of Vestmont, in the county of Cambria and Stateof Pennsylvanla, have 1nvented certain new and useful Improvegments inCar-Door Rigging; andI do here by declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertainsto make and use the,SELIDB.

" this in View, I rivet or otherwise secure directly to the bottom ofthe horizontal flange of each of the angle barstrengthening memberswhich are attached along the lower inner side of the webs of the channelcenter sills, a short section of a rolled angle cut into the desiredlength and shape, with its longer leg member vertical and extendingdownwardly therefrom, the pair of angles being preferably arranged backto back. I

"also arrange the pair of angles quite close ing angles which I provide,however, pro- 'ject inwardly and are therefore close to Specification ofLetters Patent.

gether, and by securing my pair of perforated angles to saidstrengthening angles, thispair of perforated angles have theirdownwardly projecting portions close together forming a compact, simpleand efficient bearing for the crank hubs which are journaled' therein.

As illustrated in the drawings, I have shown angle bar bracket bearingsarranged with their outwardly extending horizontal flangesattached tothe bottom of the inwardly extending horizontal flanges of thestrengthening members of the center sills. In this way theangle barbracket bearing sections have theirvertical webs disposed back to backand near enough together to allow the reduced ends of hub of the crankarm which is mounted on the inner end of the operating shaft to extendinto the perforations provided therefor in the said angle bar bearingsections. By making these hearing members out of a rolled angle bar, amuch cheaper, stronger and more rigid bearing bracket can be producedfor the same amount of metal used, than'by forming them out of pressedor cast metal.

Another object of my invention in connection with the foregoing, is toreinforce and stifien the end of the connecting lever or link which ispivotally attached to the crank arm and adapted to swing over and beyondthe operating shaft when the doors are closed, whereby the increasedstrength and weight will hold the doors more securely closed and preventundue deflection of the bentend of said lever.

Having thus given a general description of my invention, I will now, inorder to make the matter more clear, refer to the annexed one sheet ofdrawings forming part of this specification and in which like charactersof reference indicate like parts.

Figure 1 is a vertical longitudinal'sectional elevation of a portion ofa hopper bottom car taken on the line I--I of Fig. 2. Fig. 2 is avertical transverse sectional elevation taken on the line II-II of Fig.1 through the center of a car looking in the direction of the arrows.Fig. 3 is a detail side elevation showing a portion of a center sill andenough of the surrounding partsof the car to illustrate the position ofmy an- I locking-dog, also pivotally mounted on said bearing casting, bymeans of which the operating shaft is held in locked position when thedoor is closed. Fig. 5 is a vertical transverse section through thecenter of one of the angle bar bearing members, indicating in dottedlines. the cutaway portion of the horizontal leg.

Referring now to the various characters of reference on the drawings :-1indicates the car door operating shaft having its outer bearing in acasting 2 riveted to the outside hopper sheet 3 and its inner end andintermediate portions supported by bearings 4 and 5 respectively, whichare preferably cut from a rolled angle bar into the desired lengths.These angle bearing members 4 and 5 have their horizontal legs 6 rivetedor bolted to the bottom flange of the angle bar strengthening member 7,which is attached to the inner face of the web of each of the channelcenter sills 8 near the bottom edge thereof. The angle bearing members 4and 5 have their vertical legs 9 disposed back to back and areperforated centrally as at 10,

in which perforations are journaled the reduced ends 11 of the hub 12,which is mounted. on the squared inner end of the operat- 1 ing shaft 1,on which shaft is secured the crank arm 18. The outer end of said crankarm 13 is bifurcated as at 14 to receive the upper enlarged curved end15 of the lever or connecting link 16 which is pivoted thereto by meansof a pin 17 while the opposite end of the link 16 is pivotally attachedto the door spreader bar 18 by means of the eye bolt 19 provided with apivot pin 20.

The outer end of the operating shaft 1 which is journaled in the casting2 on the outside hopper sheet 3 extends beyond the same and is squaredas shown at 21 to reufactured out of rolled stock material by.

shearing the same into the desired lengths, the edges of said lengthsbeing cut on a bias, or diagonally inward from the horizontal attachingleg toward the center of the outer edge of the leg, whereby all surplusmaterial is cut away, then punching the desired perforations therein anda portion of the horizontal leg cut off as indicated in dotted lines inFig. 5 of the drawings... In forming these bearing members in thisshape, a considerable saving in weight is obtained, with out impairingtheir rigidity or strength. The peculiar formation of the curved upperend 15 of the connecting link 16, which is thrown over the shaft as thedoors are closed, insures that the doors will remain closed, even if thelocking mechanism at the outer end of the shaft becomes disarranged,

as the increased weight and stiffness of said 1 end will hold it inplace as shown in Fig. 1.

The shape and general conformation of the curved end 15 of theconnecting link let is such that when the doors are closed, the line ofpull from the doors, which extends from the center of the pivot pin 17to the center of the pivot 20, passes below the shaft 1,

so that a pull from the door, tending to open the same by swinging itdownwardly, will not open said door, but will cause the connecting link14 to press downwardly more firmly against the hub of the crank arm 18,

and thereby hold the door tightly closed, and this action is aided bythe weight and stiffness of the curved end 15 of the connecting link, asbefore stated.

While I have shown and described my in- I vention in considerabledetail, I do not wish to be limited to the exact construction speci--fied, but may use such substitutions, modifi cations or alterations asfall within the scope of my invention, as set forth in the claims.

WVhat I claim as new and desire to secure by Letters Patent is '1. In arailway car, a car door operating shaft, a crank arm mounted thereon, alongi- V tudinal center sill composed of a pair of members each having avertical web with outstanding flanges, a flanged reinforcing membersecured to each of said webs near the 1 bottom edge thereof, a shortrolled angle section, one leg of which abuts and is secured to the lowerportion of each flanged reinforcing member aforesaid, the other legs ofsaid angles extending below the centersill, and each provided with acylindrical opening therein, adapted to receive the crank i arm, andthereby form a journal bearing for the car door operating shaft.
